Application filed March 21, 1919; Serial No. 283,968.

To all 'LU/tom it may concern: Fig. 6 is -a vertical sectional view on the Be it known that we, JOHN EMANUEL line 6 6 of Fig. 8, and

JOHNSON and CHARLES H. OsLUND, citizens Fig. 7 is an elevation of a detail.

of the United States, residing at lWorcester, 5 in the county of Worcester and State ot Massachusetts, have invented a new and useful Label-Picking Device, of which the tollowing is a speeilication.

This is an improvement over, and in part a continuation of, our allowed and forfeited application Serial No. 125,268, iled October This invention relates to a mechanism 'for transferring labels from a label holder to a bottle or other article to be labeled, and applying them thereto, and while capable ot' general use isV particularly adapted for use with short labels. Tt is also adapted to be used where it is desired to'paste over so much of the surface of the labels that for that reason pickers come too close together for operation in the ordinary manner.

The principal objects of this invention are to provide a construction in which, when the pickers come closer together than the' thickness of the bottle, provision is made for enabling them to move `out of the way in a simple and convenient manner; to provide means whereby the pickers are yieldingly brought back to normal position after the bottle has passed between them, means for permitting elements oi the label holder to pass through the picker when it strikes the same, a durable and effective construct5 tion :for the picker springs and connected parts, and other Yfeatures as will appear.

This invention is designed as an improvement over the matter shown in Figures 311 to 87 of our Patent No. 1,288,718, patented August 28, 1917, but can be used independently thereof. y

Reference is to be had to the accompanying drawings, in which- Fig. 1 is an elevation of a label applying device constructed in accordance with this invention; n

Fig. 2 is an edge view of the same with parts in section on the line 2 2 of Fig. 1;

Fig. 3 is a front elevation of one of the picker supporting members;

Fig. 4L is a horizontal sectional view on the yline 1 -4 oi' Fig. 1;

Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 1;

nection with a movable bottlesupport which carries the bottlessupported in vertical position upon it and moves forward horizontally, as indicated by the arrow in Fig. e. This is preferably a rotatable support but can move in any other direction;

Tn this case,a horizontal rod 12 extends over the support 10 and carries a sliding the. rod 12' and is adapted to be operated as in our above identified patent by means of a lever 16 oscillating on an axis below the bottom of the elements shown in Fig. l, and driven in any desired way. Tt isto be understood that with the elements indicated in these drawings this sleeve 18 slides back and forth on the rod, and is also capable ot swinging about the rod for the purpose of taking the labels from a label holder not shown.

On this sleeve are a pair of bottom projections to which are ailiXed the pickersupports 17. These picker supports are rigidly connected with the sleeve 13V and will partake of all of its movements. The manner in which they are connected with it is shown. more speciiically in Fig. 2, but need not be described in detail.

pairs of pickers 19 and 20, shown as integral parts oi a plate for the body labels andneck labels respectively. Tt isfto be understood that paste is applied to what is the front surface of these pickers in Fig. 1 by a roller rolling along these surfaces, and. that the pickers then turn on the rod 12 to take labels, as torexample, those shownby dot and dash lines, from a pair of label holders not shown. They then swing back into a position in which the surfaces of the pickers are. parallel with the axis or the bottle to which the labels areI to be applied, in this case into a vertical position. Then the sleeve 13 with these pickers slides in the plane of the pickers over into a position in front of an approaching bottle. This is accomplished by the movement of the lever 16. This brings the pickers into the position shown in Fig. 1 and in full lines in Fig. 4, the labels A and B being located in position for sleeve 18. This sleeve is keyed to turn with' 0n these supports 17 are mounted twoy Thisv invention is shown as used in convin the backs of these supports.

the bottle to take them up as it moves between the pickers.

The pickers are-mounted on a. vertical shaft 21 by means of hinges 22. For the purpose of yieldingly bringing them back into the position shown in full lines in F ig. l against stops 23 carried by the supports 17, springs 24 are used extending upwardlyl ports 17 are long and narrow, and it is not desirable to have any spring supporting arms projecting from them. Ve have devised this arrangement to avoid that and to insure a long life for the springs. The channel in the front of each support is utilized as a guide for a slide 27. One end of the slide receives the end of the spring, and the other end the hook end of a wire connector 2S which passes through the perforation 25. The wire 28 is pivoted to a plate 32 on the picker plate 19 at a distance from the vertical shaft 21 on which the plate 19 is pivoted. Therefore the spring 24: yieldingly holds the slide 27 up and tends to swing the plate 19 back into contact with the stops 23.

It will be noted also that the picker plates 19 are provided with perforations 29. These are so located as to receive the hoolrs of the label magazines which hold the edges of the label. Such hooks are indicated in our above identified patent. In this way, the pickers are adapted to receive the edges of the label well within their own edges so that the label is provided with a relatively large pasted area on account of coming into contact with a great surface of the pickerplate itself, which, of course, is covered. with paste. This is an important advantage because in the ordinary constructions the label had to be of the same shape substantially as the picker plate, or at least the same shape at its edge in order to be capable of being taken from the label holder by it.

Another feature shown here consists in the provision of projections 3() mounted on and extending beyond the edge of the picker and projecting inwardly therefrom slightly for engaging the bottle andlreeping the picker y.itself away from the surface of the bottle. This is advantageous when operating with short labels to avoid applying any unnecessary paste to the bottle and to assist in causing the label to be laid out smooth upon it.

It will be seen, therefore, thatv the label pickers are capable of swinging on axes of their own carried by these supports 17 and are yieldingly pressed back so as to rest normally as near the bottle as possible against the stops 23 and to be brought back into this position after the bottle has forced them away from it as indicated in Fig. 4.

VAlthough we have illustrated and described only a single form of the invention, we are aware of the fact that modifications can be made therein by any person skilled in they art without departing from the scope of the invention as expressed in the claims. Therefore, we 'do not wish to be limited to all the details of construction herein shown and described, but what we do claim is- 1. The combination with a labelv picker support, of a shaft thereon parallel therewith, means for supporting an article to be labeled in position parallel with said shaft and adjacent thereto, a label picker carried by said shaft and adapted to swing thereon independently of said support, said support being of channel form, a spring connected with said picker, and means extending through said support to the rear side thereofl and along the same for normally swinging the picker into operative position. v

2. The combination with a label picker support having a shaft thereon, of a picker mounted to swing on said shaft, a spring connected with the picker and support for yieldingly holding the picker in operative position, anda projection extending from the picker for engaging the article to be labeled and preventing contact of the picker with said article.

3. The combination of a label picker support having a shaft thereon, of a picker mounted to swing on said shaft, a spring connected with the picker and support for yieldingly holding' the picker in operative position, and a projection extending from the picker for engaging the article to be labeled, and turning the picker back away from said article in opposition to said spring as the bottle approaches labeling position.

a. The combination of a movable picker support adapted to move into operative position, a picker movably mounted thereon, means for movably supporting the bottle adjacent tothe picker, and means movable with the support for engaging an approaching bottle and preventing the picker engaging said bottle.

5. ln a label picking device, the combination of a pair of supports, a picker plate pivoted on each support, and a longitudinally extensible spring arranged on each support parallel with the axis of the pivot thereon and connectedV with the picker plate.

6. In a label picking device, the combination of a support, a picker plate pivoted thereon, a longitudinally extensible spring arranged on the support parallel With the axis of the picker plate pivot, and connected through the support with the picker plate to hold it yieldingly back in position to engage the article to be labeled.

7. In a label picking device, the combination of a support, a picker plate pivoted on said support, a longitudinally extensible spring arranged on said support parallel With the axis of the picker plate pivot and connected With the picker plate, a slide movable on the support parallel with the length of the spring and connected therewith, and a rigid member pivotally connected With said slide and With the picker plate.

In testimony whereof We have hereunto aiiixed our signatures.
